Product Description

The AF9 Auto Filter takes the most desirable auto-wah and swept filter effects and offers them up in a compact, user-friendly package. Opto-coupler circuitry produces the shimmering, watery filtering of legendary vintage units. Threshold and Peak sliders control the degree of effect; while Range and Drive switches determine range and direction of the filter sweep. Three selectable filter types (Low Pass, Band Pass, and Hi Pass) and a frequency range of 100 Hz – 4 kHz allow the AF9 to function with virtually any instrument or input signal.

5.0 out of 5 stars Best Sounding Envelope Filter
Reviewed in the United States on October 24, 2015

This thing has alot of options, and though I'm still tinkering with it, in particular finding a way to extend out the wah on single notes as it can kind of close up to soon. I don't think that'll be an issue when I dig into the pedal as I believe it has internal trim pots to adjust levels and sensitivity, I just have to look into it.

That said, seriously, there's alot of really usable options on this thing. On almost every pedal I've used there's always one setting that's "the best", but I'm finding I can dial in "niche's" with this thing for multiple uses, which is really cool.

At any rate, this thing is really the best sounding envelope I've heard tone wise. I think it could use some very slight adjustments in regards to rate at which the filter closes & the stomp button feeling a little funky, but other than that I highly doubt anyone would be disappointed with this.

Edit:

This pedal had tone suck through my rig, which was a ts808 & ts9 running into a deluxe reverb. My thinking after the fact is that perhaps the envelope filter didn't play well with the buffers, but I may try again in the future as I did return the pedal. That said, I LOVE the sound this thing produces, and I will probably buy again in the future when I have a different setup.

3.0 out of 5 stars Great Pedal need volume control
Reviewed in the United States on December 24, 2016

The effect is terrific for what it is very funky. My particular issue is it does not have a volume adjust so then you turn it on and adjust the sound then turn when off the bypass will be too low in sound so you have to turn it back up at the amp. The only way around it is to put another effects pedal in with it to adjust the volume as it is too loud so that would work then you would nee to turn both off to bypass both. Keep that in mind. So all in all it is a great pedal but has that issue.

5.0 out of 5 stars but I go to Amazon to read reviews and would like to share my thoughts here about this pedal
Reviewed in the United States on August 19, 2015
After reading a ton of different reviews and listening to different envelope filters on youtube, I ended up choosing the Maxon AF-9. I did not buy mine at Amazon, but I go to Amazon to read reviews and would like to share my thoughts here about this pedal. I have had this pedal for approximately 3 years. If you are looking for the warmest sounding envelope filter out there, look no further. This produces a very warm "wah" sound. It is also worth mentioning that this thing is built like a tank. My brother purchased the EHX QTron pedal, and after comparing both, I am very happy with my decision. I am not in any way trying to say that the QTron is bad. It is a great pedal too and offers a wider range of tweakability than the Maxon. However, it does not produce the warmth of tone that the Maxon does. When placed after the Ibanez TS-9 (Tube Screamer), the filter really opens up and you can get very close to the Jerry Garcia (Mutron) sound. This pedal actually uses the same circuitry that the classic Mutron used. I agree with other reviewers that it would be nice to be able to have more control over the length of the envelope effect, but in the end, I cannot let this detract me from giving this sweet pedal 5 stars. It has the tone.

5.0 out of 5 stars Great tone
Reviewed in the United States on August 17, 2016
I found it at a good price and replaced my qtron plus. Love it - much more usable tone for rhythm than the qtron. I use it with a little boost so the effect works well with vintage single coils. With a little adjustment varying pick attack opens the fllter nicely. Wish someone would by my qtron.

5.0 out of 5 stars WOMP WOMP! Jerry Garcia is here...
Reviewed in the United States on May 15, 2010
Hey NOw! I love this pedal. Along with some MXR distortion+ you can get a great Jerry sound. I haven't played the MuTron though. The only thing I would change is adding an ability to change the length of the swell of the effect. To make it shorter or longer. My guess is I can open it up and do this but Im not sure. I got mine Used for $100. and it is the best value pedal I have bought.
